Healthy High-Protein Strawberry Rhubarb Overnight Oats - featured image

A quick and easy high-protein overnight oats recipe combining the tartness of rhubarb with the sweetness of strawberries, Greek yogurt, and protein powder for a nutritious and satisfying breakfast.

Ingredients

Scale
  • 1 cup (90g) rolled oats (old-fashioned)
  • 1/2 cup (75g) fresh or frozen strawberries, hulled and sliced if fresh
  • 1/2 cup (75g) rhubarb stalks, chopped
  • 1/2 cup (120g) plain Greek yogurt (full-fat preferred)
  • 1 cup (240ml) milk (dairy or plant-based such as almond, oat, or soy)
  • 1 scoop (about 30g) vanilla protein powder
  • 1 tablespoon chia seeds
  • 1 tablespoon maple syrup or honey (optional)
  • 1 teaspoon lemon zest
  • 1/2 teaspoon cinnamon
  • Pinch of salt

Instructions

  1. Chop rhubarb into small 1/4-inch (0.6 cm) pieces and slice strawberries if fresh. If using frozen fruit, thaw slightly or add directly for a softer texture overnight.
  2. Cook the rhubarb lightly (optional): In a small saucepan, combine rhubarb, 1 tablespoon water, and half the maple syrup or honey. Cook on medium heat for 3-4 minutes, stirring occasionally until softened but not mushy. Let cool.
  3. In a mixing bowl, combine rolled oats, chia seeds, cinnamon, lemon zest, and a pinch of salt. Stir well.
  4. Pour in Greek yogurt, milk, vanilla protein powder, and the remaining maple syrup or honey. Whisk thoroughly to avoid clumps and distribute flavors evenly.
  5. Gently stir in the cooked rhubarb and sliced strawberries, reserving a few pieces for topping later.
  6. Divide the mixture evenly into mason jars or airtight containers. Leave some space at the top for expansion.
  7. Seal lids tightly and place in the fridge for at least 6 hours or overnight to allow oats to absorb liquid and thicken.
  8. In the morning, give the oats a gentle stir, add the reserved fruit on top, and enjoy cold or warmed briefly in the microwave (about 30 seconds). Optionally, sprinkle with nuts or seeds for extra crunch.

Notes

Use old-fashioned rolled oats for best texture; avoid instant or quick oats to prevent mushiness. Cooking rhubarb softens tartness and improves texture but can be skipped. Mix protein powder with milk first to avoid clumps. Add a splash of milk in the morning if oats are too thick. Swap Greek yogurt and protein powder for plant-based alternatives for vegan version. Store in fridge up to 4 days. Warm briefly if preferred.
